Is there a file size limit?
There is no server upload limit because files are processed locally. Very large files may still be limited by your browser, available memory, and device performance.
What the result changes
A lower bitrate stores less audio information and creates a smaller download. This change is lossy and cannot be reversed by later converting the MP3 into a larger format.
Check before you finish
Listen with headphones to speech consonants, cymbals and quiet passages. Confirm the whole duration is present and keep the source or a lossless master for future editing.
